Onan Generator QG 5500 Help
Hello,
Does anyone have an Onan QG 5500 generator? If so, could you check the fuel line check valve for me? I am wanting to know if the arrow on the check valve is pointing up towards the carburetor or down back towards the tank on their unit for me. Also, could you verify if the the check valve is on the return hose or the supply?
I have been dealing with an issue that when the fuel tank gets hot from the ambient air and pressurizes, fuel is being forced into the generator and flooding the cylinders and oil sump. Oil/gas is then leaking from the exhaust out the the exhaust pipe or overflowing the oil reservoir. I added a shut off valve to the supply side thinking it was how the fuel was flooding the unit, but apparently it is coming from the return side. The arrow on my check valve is installed facing the top of the engine which I believe is the wrong direction.
Here is a picture of how my check valve is installed. Unit was purchased new.
